change this:

   setState(() {
      categories = data;
      _currentCategory =  categories[0].data['category'];
    });

into this:

   setState(() {
      categories = data;
      _currentCategory =  categories[0].data()['category'];
    });

In the latest update for the firebase plugins, data() is a method now.
